The 11th international conference on Direct Reactions with Exotic Beams (DREB2020) is part of the biennial series, which began in 1999 at MSU, East Lansing, at the initiative of physicists working in the field from MSU, IPN-Orsay, and FSU. The following meetings were held at Orsay (2001), Guildford (2003), East Lansing (2005), Wako (2007), Tallahassee (2009), Pisa (2012), Darmstadt (2014), Halifax (2016), and Matsue (2018). The scientific program is devoted to the latest experimental and theoretical research and developments in nuclear reactions with exotic nuclei. The topics will include the following subjects relevant to direct reactions:

• Nuclear astrophysics
• Spectroscopy of exotic nuclei, drip-line and unbound nuclei
• Nuclear force and Short-range correlations
• Advances in direct reaction theory
• New instrumentation for direct reaction studies
• Ab-initio methods for structure and reactions
• Clustering phenomena probed by nuclear reactions

Junior Duality and Integrability Workshop is a three-day workshop open to PhD and early career researchers interested and/or working in duality invariant formalisms, integrable models, and related subjects.

The workshop will take place online, from the15th-17th of February 2021.

The goal is to offer overview talks in the fields of T/U-duality and integrable models as an addition and counterpart to the various seminar series. The speaker list can be found on the website. Next to the overview talks, PhD students can apply to present their work in a gong-show format. To complement scientific discussions, two talks will offer guidance on how you can shape your future in- or outside academia. Finally, participants will be given a platformthrough slack channels and gather.town in orderto ask questions freely and network together, both during the workshop and--perhaps--in the future.

Several scenarios of physics beyond the Standard Model involve hidden strongly-coupled gauge sectors. Cosmological first-order phase transitions predicted by strongly-coupled gauge theories may trigger the production of gravitational waves. As a result, the newborn gravitational wave astronomy constitutes a promising tool for probing beyond Standard Model physics. In this talk, I will discuss how top-down holography can be deployed to compute the spectra of gravitational waves coming from confinement/deconfinement and chiral symmetry breaking/restoration cosmological first-order phase transitions.

A recurrent idea since the early days of holography is a somewhat implicit relation between notions of ‘complexity’ of quantum states and the degree of ‘gravitational clumpling’ in the bulk. Holographic complexity, in the guise of the Complexity = Volume prescription, comes equipped with a natural correspondence between its rate of growth and the average infall momentum of matter in the bulk.  This Momentum/Complexity correspondence can be related to an integrated version of the momentum constraint of general relativity.  Furthermore, we propose a generalization, using the full Codazzi equations as a starting point, which successfully accounts for purely gravitational contributions to infall momentum.

There is an intriguing connection between integrable sigma-models and Poisson-Lie (PL) symmetry. As I will review, the latter is manifest in the E-model, rendering it a powerful tool to construct a variety of integrable models which recently have been identified with surface defects in 4d Chern-Simons theory. Manifest PL symmetry facilitates computations which would be forbiddingly complex without it. Important examples, which I will discuss in detail, are one and two-loop beta-functions. We will see that they underpin a deep connection between classical integrability and the corresponding quantum regime. Based on arXiv:2012.10451 and arXiv:2011.15130 with Thomas Rochais.

I will show that there is a wide class of integrable sigma models, which includes CP^{n-1}, Grassmannian, flag manifold models, that are equivalent to bosonic (and mixed bosonic/fermionic) chiral Gross-Neveu models. The established equivalence allows to effortlessly construct trigonometric/elliptic deformations, provides a new look on the supersymmetric theory and on the cancellation of anomalies in the integrability charges. Using this formalism, we develop criteria for constructing quantum integrable models related to quiver varieties. Based on arXiv:2006.14124 and arXiv:2009.04608.

The search for New Physics at colliders can take many shapes, and while direct searches for new particles are definitely a necessity, a strong program of precision measurements together with precision calculations of the Standard Model predictions could bring us information on beyond Standard Model physics even if the LHC does not see any new resonance. I will review some of the advantages and drawbacks of this approach, focusing in particular on the measurement of the Higgs potential and the use of Effective Field Theories. With this talk I wish to introduce myself to the Department and give a comprehensive, but not too detailed, description of my research.
